Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for acquiring information associated with media content displayed on large screens are inefficient, as they require complex user operations, consume significant network resources, and are prone to errors due to the use of two-dimensional codes, which affect aesthetic quality and accuracy.
Innovation Solution
A computer-implemented method and apparatus that broadcast a communication address from a playing device, allowing user terminal devices to connect and request information associated with media content, using identifiers such as network addresses or file names, enabling efficient and accurate information retrieval without the need for authenticated connections or precise scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a two-dimensional code is inserted in the image picture displayed on the large screen, then users can acquire additional information about the image, but the completeness of the image is affected and its aesthetic appearance deteriorates
Solution Approach 1:
The patent extracts the information delivery function from the visual display by using audio signals (speech synthesis) to convey product information instead of embedding visual codes in the displayed image. This separates the information transmission task from the aesthetic display, eliminating the conflict between information completeness and visual quality.
Solution Approach 2:
The patent introduces an intermediary device (portable terminal with speech synthesis capability) that receives data from the large screen and converts it into audio form. This intermediary transforms the information delivery mechanism from visual (code scanning) to auditory (speech output), preserving both image integrity and information accessibility.
2Loss of information
If a two-dimensional code is used for information acquisition, then users can access additional information, but the scanning process takes a long time and may fail if the code disappears before scanning is completed
Solution Approach 1:
The patent replaces the mechanical scanning process (manual positioning and scanning of visual codes) with an automated data transmission system. The large screen directly transmits product data to portable terminals via wireless communication, and the terminal automatically converts and outputs the information as speech, eliminating the time-consuming manual scanning process entirely.
Solution Approach 2:
The patent performs preliminary data preparation by pre-processing product information into a format suitable for wireless transmission and speech synthesis. This preliminary action ensures that information is ready for immediate delivery upon user request, eliminating delays associated with real-time code scanning and processing.
3Measurement precision
If a two-dimensional code is used for information acquisition, then users can access additional information, but accurate scanning requires the portal terminal to be aimed at the code zone, which is difficult to maintain among multiple users at different angles and distances
Solution Approach 1:
The patent creates a universal information access system where the large screen serves multiple functions: displaying visual content, transmitting data wirelessly, and providing audio output. Any user with a compatible portable terminal can access information from any position without needing to align or aim at a specific code zone, making the system universally accessible to all users regardless of location.
Solution Approach 2:
Instead of requiring users to actively scan and locate codes on the screen, the patent inverts the interaction model: the large screen actively transmits information to portable terminals that are within range. This passive reception approach eliminates the need for precise aiming and positioning, greatly simplifying user operation.
4Loss of information
If users log into the network using a portable device to search for product information, then users can acquire information, but the process requires complicated operations and consumes huge network resources
Solution Approach 1:
The patent implements a self-service information delivery system where the large screen automatically provides product information to portable terminals upon simple user initiation. The system handles data retrieval, processing, and conversion automatically without requiring users to perform complex search operations, making the process as simple as pressing a button or approaching the screen.
Solution Approach 2:
The patent merges multiple functions into a unified system: the large screen combines visual display, wireless data transmission, and product information storage; the portable terminal combines wireless reception, data processing, and speech synthesis. This integration eliminates the need for separate search operations and reduces overall system complexity while maintaining information accessibility.

AI summary
Systems and methods are provided for providing information associated with media contents are provided. The method comprises broadcasting a communication address associated with a playing device configured to play the media contents, the broadcasted communication address enables a user terminal device to communicate with the playing device; receiving, from the user terminal device, a request to acquire information associated with the media contents; determining an identifier associated with the information; and transmitting the identifier to the user terminal device. The identifier enables the user terminal device to acquire the information.
